Abstract (en)
The present invention relates to a haymaking machine comprising a plurality of tedding and/or windrowing rotors which are connected to a carrier frame composed of a central section and of lateral sections articulated on one another. <??>According to the invention, each lateral section (3, 4) is composed of three parts (22, 23, 24) which each carry a rotor (9) and which are articulated on one another by means of axles (25 and 26) pointed in the direction of advance of the machine. Each of these parts (22, 23, 24) is displaceable through an angle of approximately 90 DEG about its axle of articulation (5, 6, 25 or 26) on the central section (2) or the adjacent part, in such a way that they can be folded substantially in the form of an upturned U. <IMAGE>
Abstract (fr)
La présente invention se rapporte à une machine de fenaison comportant plusieurs rotors de fanage et/ou d'andainage qui sont reliés à un bâti porteur composé d'un tronçon central et de tronçons latéraux qui sont articulés entre eux. Selon l'invention, chaque tronçon latéral (3, 4) est composé de trois parties (22, 23, 24) portant chacune un rotor (9) et qui sont articulées entre elles au moyen d'axes (25 et 26) dirigés dans la direction d'avancement de la machine. Chacune de ces parties (22, 23, 24) est déplaçable d'un angle d'environ 90° autour de son axe d'articulation (5, 6, 25 ou 26) avec le tronçon central (2) ou la partie voisine, de telle sorte qu'elles soient repliables sensiblement en forme de U renversé.
